[PATCH] backup.pl: Create the new unbound user and group when doing a restore

[Adolf Belka]

- With the introduction of the unbound user and group, when a restore is done from a
   earlier backup when user and group nobody were used then the unbound user and group
   are removed as passwd and group are backed up.
- Using the entry already present for the dhcpcd user and group I cre4ated this patch.
- Not 100% certain it is the correct way to do it, as I am not sure about if a restore
   is done where the unbound user and group already exist but presumably the same effect
   occurs with the dhcpcd user and group.

Hello Adolf,

Thanks for the patch, but I am not sure whether we strictly need it. Maybe we need it for a reason I am not aware of.

So if someone restores a backup from an older version, the new user should already exist as we create it in the updater. Nothing to do during the restore. If someone is taking a backup created on c202 and takes it back to lets say c199, then there is no Unbound user and the files have the wrong ownership but there is nothing we can do about it.

All the best,
-Michael
